MatMumpsSetSchurIndices

 Set indices defining the Schur complement that MUMPS will compute during the factorization steps

Synopsis

#include "petscmat.h"  
PetscErrorCode MatMumpsSetSchurIndices(Mat F,PetscInt size,PetscInt idxs[])
Logically Collective on Mat

Input Parameters

F - the factored matrix obtained by calling MatGetFactor() from PETSc-MUMPS interface
size - size of the Schur complement indices
idxs[] - array of Schur complement indices

Notes

The user has to free the array idxs[] since the indices are copied by the routine. MUMPS Schur complement mode is currently implemented for sequential matrices.
